As far as I know, graphics.h is an old obsolete Borland C++ header file for graphics in Ms DOS OS. I think the last Borland C++Builder no longer supported graphics.h. However graphics.h has been simulated for Windows. Executables made using graphics.h usually don't work in newer PCs (and laptops with Windows OS).

(Although graphics.h has simple to use graphical functions, using it is no longer recommended/supported)

Also open source C++ compilers usually do not support conio.h.

conio.h has most functionality in Borland compilers. It's also supported in MS VC++, but with less functionality. conio.h is not supported in gcc, etc.

@REGZEN: Yes there are alternatives. ncurses is a package which provides functions you need. Also if you don't like to use it getch and kbhit can be written using other functions if you need them. yes for sure.
